This patch adds the possibility to obtain MAC temperature via hwmon.
On A1 there are two separate temperature sensors.
On A2 there's only one temperature sensor, which is used for reporting
both MAC and PHY temperature.

This patch adds support for FW 4.x, which is about to get into the
production for some products.
4.x is mostly compatible with 3.x, save for soft reset, which requires
the acquisition of 2 additional semaphores.
Other differences (e.g. absence of PTP support) are handled via
capabilities.
Note: 4.x targets specific products only. 3.x is still the main firmware
branch, which should be used by most users (at least for now).

This patch fixes ip dst and ipv6 address filters.
There were 2 mistakes in the code, which led to the issue:
* invalid register was used for ipv4 dst address;
* incorrect write order of dwords for ipv6 addresses.

This patch adds initial support for mqprio rate limiters (max_rate only).
Atlantic HW supports Rate-Shaping for time-sensitive traffic at per
Traffic Class (TC) granularity.
Target rate is defined by:
* nominal link rate (always 10G);
* rate factor (ratio between nominal rate and max allowed).

This patch contains the following changes:
* access cfg via aq_nic_get_cfg() in aq_nic_start() and aq_nic_map_skb();
* call aq_nic_get_dev() just once in aq_nic_map_skb();
* move ring allocation/deallocation out of aq_vec_alloc()/aq_vec_free();
* add the missing aq_nic_deinit() in atl_resume_common();
* rename 'tcs' field to 'tcs_max' in aq_hw_caps_s to differentiate it from
the 'tcs' field in aq_nic_cfg_s, which is used for the current number of
TCs;
* update _TC_MAX defines to the actual number of supported TCs;
* move tx_tc_mode register defines slightly higher (just to keep the order
of definitions);
* separate variables for TX/RX buff_size in hw_atl*_hw_qos_set();
* use AQ_HW_*_TC instead of hardcoded magic numbers;
* actually use the 'ret' value in aq_mdo_add_secy();

GPIO PIN control and access is done by direct phy manipulation.

via MDIO access mailbox.

We implement HW filter reservation for PTP traffic. Special location
in filters table is marked as reserved, because incoming ptp traffic
should be directed only to PTP designated queue. This way HW will do PTP
timestamping and proper processing.

Basic HW functions implemented for adjusting frequency,
adjusting time, getting and setting time.
With these callbacks we now do register ptp clock in the system.
Firmware interface parts are defined for PTP requests and interactions.
Enable/disable PTP counters in HW on clock register/unregister.

>From HW specification to correctly reset HW caches (this is a required
workaround when stopping the device), register bit should actually
be toggled.
It was previosly always just set. Due to the way driver stops HW this
never actually caused any issues, but it still may, so cleaning this up.

Default LRO HW configuration was very conservative.
Low Number of Descriptors per LRO Sequence, small session
timeout, inefficient settings in interrupt generation logic.
Change max number of LRO descriptors from 2 to 16 to
increase performance. Increase maximum coalescing interval
in HW to 250uS. Tune up HW LRO interrupt generation setting
to prevent hw issues with long LRO sessions.

David noticed the original define was hiding 'err' variable
reference. Thats confusing and counterintuitive.
Andrew noted the whole macro could be replaced with standard readx_poll
kernel macro. This makes code more readable.

Recently the maximum number of queues was increased up to 8, but
NIC was not fully configured for 8 queues. In setups with more than 4 CPU
cores parts of TX traffic gets lost if the kernel routes it to queues 4th-8th.
This patch sets a tx hw traffic mode with 8 queues.

IOMMU fault may occurr on unbind/bind or if_down/if_up sequence.
Although driver disables the rings on down, this is not enough.
Due to internal HW design, during subsequent initialization
NIC sometimes may reuse RX descriptors cache and write to the
host memory from the descriptor cache.
That's get catched by IOMMU on host.
This patch invalidates the descriptor cache in NIC on interface down
to prevent writing to the cached descriptors and to the memory pointed
in those descriptors.

Systems with large MRRS on device (2K, 4K) with high data rates and/or
large MTU, atlantic observes DMA packet buffer overflow. On some systems
that causes PCIe transaction errors, hardware NMIs or datapath freeze.
This patch
1) Limits MRRS from device side to 2K (thats maximum our hardware supports)
2) Limit maximum size of outstanding TX DMA data read requests. This makes
hardware buffers running fine.
